我有 json 对象，但我无法访问其中的"名称"元素？



这是JSON数据。当我解析时，这是行不通的。但是现在它有效。

{＆quot" 2＆quot"：{＆quot"餐厅"：" naushijaan＆quot"＆quot" order＆quot"＆quot"交付" at'：＆quot" 11：10 AM 2016-06-18＆quot ,,"类型"＆quot" name"：; quot" abc ddd＆quort ,，＆quot"地址"：" 12356，勒克瑙，226010"＆quot'＆quot＆quot" 677777799999＆quot，＆quot"总计"：" 545.00卢比"付费"由管理员挑选"日期"：＆quot" 06/18/2016"＆quot"状态＆quot"：{＆quot" processing＆quot"：2，"交付"：3，＆quot"已完成＆quot"：4，"失败"：5}，，"行动"："视图"}，，＆quot" 3＆quot"：{＆quot"餐厅"：＆quot" aahaar"＆quot" order＆quot"＆quot"交付"：＆quot" 11：32 AM 2016-06-12＆quort＆quort"类型"＆quot" name"：" sk mishra＆quot"＆quot"地址"：＆quot" 520Viram Khand，Lucknow，226010"电话"：＆quot" 6799999999"＆quot"总计"：" 450.00卢比"付费"由"：＆quot"摘自"虚拟"＆quot"日期"：＆quot" 06/12/2016"＆quot"状态＆quot"：{＆quot"已完成＆quot"：4，"失败"：5}，，"行动"："视图"}，

}

这就是您可以访问名称字段的方式。

您的JSON是一个对象，要访问名称，您必须通过属性迭代：

$.each(data, function(i, e) {
  alert(e.name);
});

如果已经是JSON的对象，请访问它：

var data = {"0":{"restaurant":"Bayleaf","order":"HIHUN10","delivery at":"04:43 PM 2016-06-22","type":"Home Delivery","name":"dEEPAK rAI","address":"12356,Lucknow,226010","phone":"9120276440","total":"Rs 831.60","pay by":"Cash On Delivery","picked by":"By Administrator","date":"06/22/2016","status":"Waiting","action":"pending"},"1":{"restaurant":"Jungliee","order":"HIHUN9","delivery at":"03:40 PM 2016-06-21","type":"Home Delivery","name":"dEEPAK rAI","address":"12356,Lucknow,226010","phone":"9120276440","total":"Rs 465.00","pay by":"Cash On Delivery","picked by":"Dummy","date":"06/21/2016","status":{"Accepted":1,"Processing":2,"Delivered":3,"Completed":4,"Failed":5},"action":"view"},"2":{"restaurant":"Naushijaan","order":"HIHUN8","delivery at":"11:10 AM 2016-06-18","type":"Home Delivery","name":"dEEPAK rAI","address":"12356,Lucknow,226010","phone":"9120276440","total":"Rs 545.00","pay by":"Cash On Delivery","picked by":"By Administrator","date":"06/18/2016","status":{"Processing":2,"Delivered":3,"Completed":4,"Failed":5},"action":"view"},"3":{"restaurant":"Aahaar","order":"HIHUN7","delivery at":"11:32 AM 2016-06-12","type":"Home Delivery","name":"sk mishra","address":"520viram khand,Lucknow,226010","phone":"9198979962","total":"Rs 450.00","pay by":"Cash On Delivery","picked by":"Dummy","date":"06/12/2016","status":{"Completed":4,"Failed":5},"action":"view"},"4":{"restaurant":"Bayleaf","order":"HIHUN6","delivery at":"08:29 PM 2016-06-11","type":"Home Delivery","name":"Dharmraj","address":"D-242Office G 19 Sector 63,Lucknow,201003","phone":"7428069025","total":"Rs 606.60","pay by":"Cash On Delivery","picked by":"By Administrator","date":"06/11/2016","status":{"Completed":4,"Failed":5},"action":"view"},"5":{"restaurant":"Bayleaf","order":"HIHUN5","delivery at":"08:17 PM 2016-06-11","type":"Home Delivery","name":"Dharmraj","address":"D-242Office G 19 Sector 63,Lucknow,201003","phone":"7428069025","total":"Rs 606.60","pay by":"Cash On Delivery","picked by":"By Administrator","date":"06/11/2016","status":{"Completed":4,"Failed":5},"action":"view"}};
// as single, hardcoded entry
var nameAt0 = data[0].name;
var nameAt1 = data[1].name;
...
// as loop
for( var i in data )
    if( data.hasOwnProperty(i) )
        var name = data[i].name;

它的工作正常，现在每个答案都正确。我缺少

 dataType: 'json'
   ,

'datatype：json'侧ajax块。

首先，您有一个非常非明显的JSON结构，但是，您无法作为JSON数组访问，因此，您必须将JSON解析为OBJET，您可以阅读更多信息很简单。

    var MyJSONArray = [];
    $.each(YourJSON,function(index,e){
        MyJSONArray[] = e;
    ]

然后您可以将其用作

    var restarant_1 = MyJSONArray[0].restaurant;

就是这样！享受
